Skip Pre-auth check when VIP = 1

Hello, I have the following code, each user must have a linked credit card, upon a Refund or a payout, there will be a pre-auth check, the problem here is that I need to add the condition but I believe I misplaced it, please take a look.
General information
VIP == 0 means check for card pre-auth
VIP == 1 Skip pre-auth and issue the refund or payout.

public function postProcess(){
	$idRequest = (Tools::getValue('id_request'));
	$id_Seller = Db::getInstance()->getValue('SELECT id_seller FROM '._DB_PREFIX_.'mangopay_wk_seller_refund_request WHERE id_request=' . $idRequest );
	//var_dump($id_Seller) => it will return user id = 7 as expected so the query is valid;
	$isVIP = Db::getInstance()->getValue('SELECT vip FROM '._DB_PREFIX_.'wk_mp_seller WHERE id_seller=' . $id_Seller);
	//var_dump($isVIP) => will return 1 as the user is VIP enabled;

                }
            }
        }
    }
    parent::postProcess();
}

Please look at this line:
if (Tools::isSubmit(‘request_approve_button’)) {

Orginal statement is

if ($objRequest = new MangopaySellerRefundRequest($idRequest)) {

I changed it to

if ($objRequest = new MangopaySellerRefundRequest($idRequest,$isVIP == 1)) {
